New Car Break-In Process...

I've never followed the break-in procedure of any car I've bought, and never encountered an issue with any either.

Thanks Sam, yeah I have already broken a few of the general rules on break-in and it all seems to be running fine. I can't restrain myself for 1000 miles that is just far too long and I do a lot of driving including highway miles for work purposes so I need to drive it rather than taking it easy for far too long. lol

The only new car I had was a Dodge Neon srt-4. I went WOT right out of the dealership the moment paperwork was completed. By that weekend I had an adjustable wastegate to increase the boost and catless downpipe. Later on I went big turbo and roll raced it countless times. And up until 47k miles when I sold it there wasn't a single problem with the engine.

I had an SRT-4 as well, I actually had the NEON first and then switched to the Caliber. I loved those cars, and I did not have a single defect or complaint with either of them, they were very reliable for me, and I had lots of fun with both of them. They were actually more reliable than the Hondas I owned at the same time (in terms of factory defects) so no complaints on my part. I still remember rolling out the dealer with my shiny new blue Neon srt-4, it had the best sounding factory exhaust for any 4 banger I know.

At that time Dodge/Chrysler actually recommended running high throttle position as soon as possible in higher gears to promote good ring seating for the first 200 miles or something like that. To me that is a proper break-in procedure.

I've broken in all my Subaru's like I do with any motor. Varied load, some boost, and engine braking. Never had an issue with ringlands or oil consumption. I also tune a lot of Subaru's and I give the same advice..

that's what we need a very simple process that makes sense, the more I read the factory recommendation the less I believe it. I sometimes think they suggest that type of a break-in process so they can keep accurate statistics when engines happen to fail, and if they can have a large number of owners following the same spec it eliminates some of the variation when it comes time to diagnose failures.
